Default Can a Macintosh person tell us how to change the name of a file?

Actually MS came up with the ill-fated, bad idea of
ADS to help accomodate MS Office to Macs. Later they
did some dumb things like using them to store metadata.
But whaddayaknow.... it turned out the metadata was
lost if the file was moved from an NTFS file system.

(Actually that's a handy way to clean ADS. Move them
to a FAT32 partition.)

There's nothing "costly" about opening a file in
a hex editor. HxD uses about 8 MB of RAM. Pale
Moon, by contrast, is costing me 100+- MB just
to sit there.

I do it when I need to. Not a big deal. We're
talking about scenarios where the file type is
unknown. I don't find that happens very often.

If you don't know what to do with "every
single file" then even MacOS handholding
won't help.
